DISPENSER AND DISPENSING METHOD

摘要

PROBLEM TO BE SOLVED: To improve accuracy in dispensation of a liquid from a hermetically sealed liquid container without complicating a device.SOLUTION: Pressures inside and outside a hermetically sealed liquid container are measured by a pressure sensor connected to a dispensing probe, and a manipulated variable of a pump is corrected in accordance with measured pressure levels. Correcting the manipulated variable of the pump is performed by calculating a deformation volume of a dispensation flow passage due to pressure variation.
